STREET-LANTERN.

SPECIFICATION forming part of Letters Patent No. 435,795, datedSeptember 2, 1890.

Application filed November 4, 1889. Serial No. 329,136. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM P. BUTLER,a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Street-Lanterns, of which thefollowing is a specification.

The invention has for its object to provide novel means for permanentlyuniting the top and bottom glass-carrying frame-sections of a lantern bya self-locking joint or connection, whereby soldering, spinning, andlike fastening mediums are avoided and the cost of manufacture isreduced.

To accomplish this object my invention consists in the features ofconstruction and combination of devices hereinafter described andclaimed, reference being made to the accompanying drawings, in which-Figure 1 is a side elevation, part in section, of a street-lanternconstructed according to my invention. Fig. 2 is a detail brokenperspective view of the top glass-carrying framesection of the lantern.Fig. 3 is a similar View of the bottom frame-section of the same. Fig. 4is a horizontal sectional view taken on the line co co, Fig. 1. Fig. 5is a detail transverse sectional view of one of the corner-posts 011 anenlarged scale, and Fig. 6 is a broken perspective View of one endportion of a corner-post on an enlarged scale.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein- The numeral 1 indicates the glass panes, secured attheir adjacent edges in the cornerposts, and 2 indicates thelantern-door, hinged at 3 and provided with a fastening'catch at 4. Thepost to which the door is hinged and the post against which the doorcloses may be of the form shown. The corner-posts are each composed of astrip of sheet metal bent to form a flat wall 5 and two flat side walls6, Figs. 5 and 6, arranged at acute angles to the wall 5 and convergingoutwardly and resting one against the other, as at 7, beyond which pointof contact the converging walls are bent around in opposite directionstoward the wall 5 in such manner as to form two longitudinal hookedflanges 8, which are respectively parallel, or substantially so, to theexternal surfaces of the converging walls. The upper and lower ends ofthe corner-posts are soldered or otherwise secured to the end portion ofthe lower framesection of the lantern, and the corner-posts of the topframe-section or crown of the lantern are secured to the top and bottomportions of such top section or crown. The corner-posts may be providedat each end with a vertical slot 8 at the junction of the walls 5 and 6to slip over vertically-arranged portions at the corners of the endframe of the lantern, after which the posts are soldered or similarlysecured together.

The top glass-carrying frame-section or crown of a street-lantern isusually made sepa rate from the bottom glass-carrying framesection, andto provide a simple construction of parts whereby the top section orcrown can be slipped down over the upper end of the bottom section andbe automatically locked permanently thereto I construct the upper end ofthe bottom frame-section with horizontal or substantiallyhorizontal sideflanges 9, from the outer edges of which depend vertical or nearlyvertical wings 10, which are adapted to spring laterally outward bytheir inherent elasticity. The spring or elastic wings are preferablystrengthened along the inside by a bead formed by turning the metal asat 12 or otherwise. The top frame-section is constructed at the sideswith horizontal flanges 13, from the outer edges or portions of whichdepend vertically-arranged flanges 14, such flanges comprising aright-angled substantially rigid frame at the lower portion of the topsection. The lower horizontal edges of the flanges 1e are each providedat its inner side with a locking rim or bead 15, which may be formed inany suitable way, but which, as shown, is formed by turning the edge ofthe metal upward into a rim. The horizontal flanges 9 of the bottomsection constitute a base or support for the horizontal flanges 13 ofthe top frame-section, and when the latter is forced down into positionthe rims or beads 15 press the wings 1O laterally inward until said rimsor beads fall beneath the lower edges of the wings, when the latter willby their inherent elasticity spring outward and by their lower edges orbeads 12 or beads and adapted to slide over and be automatically engagedby the spring-wings when slid thereupon for permanentlyuniting theparts, substantially as described.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
